METAL-WORKING MACHINE.

To all whom it may concern:

Be it known that I, HENRY WV. E. MAR- ing at Flemington, in the codnty of Hunterden and State of New Jersey, have invented a new and useful Metal-lVorking Machine, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed for bending and shaping metal and is of use primarily, but not exclusively, for fashioning the heel calks on horse shoes, the construction being such that the heel or the shoe may be permitted to expand at the point where the constituent material of the shoe is bent to form the calk.

The invention aims to provide a device which will carry out the operation above mentioned. in an expeditious manner and with a minimum number of parts, novel means being provided for maintaining the material properly adjusted, so that it may be bent and shaped as aforesaid.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combina tion and arrangement of parts andin the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing :Figure 1 shows the invention in side elevation; Fig. 2 is a top plan; Fig. 3 is a longitudinal sec tion; Fig. at is a detailed perspective view showing a part of the bending lever; Fig. 5 is a fragmental perspective showing a portion of the die which is carried by the bending lever; Fig. 6 is a perspective showing a portion of the compression member which serves to hold down the material while the same is being bent; Fig. 7 is a fragmental perspective showing a strip of material adapted to be operated upon in the present machine; Fig. Sis a perspective showing the completed product which the machine is adapted to produce; Figs. 9 and 10 represent respectively the element shown in Fig;

8, in plan and in side elevation.

Referring to Fig. 8 of the drawings, there is indicated at 1 the heel of a horse shoe, the end of which is laterally enlarged as Specification of Letters Patent.

shown at .2. and is provided with :1 depending The nume'al 4 in Fig. 7 of the drawings indicates the heel of the shoe, be fore the same has been bent in the machine to be described hereinafter.

Although, for the purposes of illustration it has been presupposed that the machine is to be employed in the shaping of the heel of a horse shoe, the device may be used for other purposes and a skilled, mechanic will understand that, for instance, the cross section of the part 1 or l, the particular shape of the end 2, and the outline of the part 3 may all be changed without jeopardizing the utility of the invention. When those parts of the machine are described, which operate immediately to produce the elements 2 and 3, it will be understood, without further description, that such parts may be altered and shaped as may be desired, to produce the altered or required contour in the parts 2 and 3.

In constructing a machine adapted to carry out the ends in view and above described. there is provided a bed denoted generally by the numeral 5 and if desired com prising superposed members 6 anl 6. The bed 5 may be upheld at one end by a support 7, and at its opposite end may be upheld by a support 8, the latter if desired being in the form of an anvil. Upon one end of the bed 5 is mounted a base 9. A mechanism is provided which cooperates with the base 9 and this mechanism may be duplicated, if desired, at both ends of the machine, two of the bases 9 being shown in order to render it evident that such duplication is possible. lVhen two of the structures hereinafter described are used, that is, when the machine is double ended, the support 7 is preferably re placed by another anvil 8.

To the sides of the base 9 cars 11 are attached, the base being held in place by means of securing devices 10 and the ears 11 being held to the base by means of securing elements 12. The ears 11 carry pivot members 1.4 upon which are mounted to swing bars 15 provided with fingers 16. The fingers 16 are adapted to cooperate with the upper edges of the ears 11 to efi'ect a cutting or shearing of material. This operation, however, has nothing to do with the main func tion of the machine as hereinafter described, and will not be alluded to hereinafter. Located between the bars 15 is an angular lever 17 comprising arms 18 and 19 disposed at right angles to each other, the arm 18 being held to the bars 15 by means of securing elements 100. The arm 19 of the lever 17 is in the form of a channel and at one end is provided with stop flanges 20. Disposed within the contour of the arm 19 and abutting against the stop flanges 20 is a die 21 held in place by means of a screw 22 or otherwise. In the forward face of the die 21 is a longitudinal groove 23 pr ovided sition, as shown in Fig. 3 of the drawings.

It is obvious that the bar of metal cannot move endwise in one direction, because it is gripped by the angle member 37 on the arm and the base 9. Neither can the bar of metal move in an opposite direction, because it is in abutment with the stop 25. hen the angle lever 17 is swung upwardly in the manner above described, the calk 3 at one end with an enlargement 21 whiehagfgrpied and, at the same time, the metal may be shaped as desired. Mounted in the groove 23 is a stop 25 having a longitudinal slot 26 through which passes a set screw 27 engaging the die 21.

Mounted on the bed 5 is a support or gage 28 held in place adjustably by means of a bolt 29 passing through an elongated slot 30 formed in the bed 5. Disposed to the rear of the support or gage 2S and preferably formed integrally with the upper member 6' of the bed 5 are ears 31 supporting a shaft 4 32 constituting a pivotal mounting for a socket 33 in which is threaded as shown at 35 for longitudinal adjustment a compression member or arm 34. Applied to the free end of the arm 3% is a pressure plate 36 preferably in the form of an angle member, held in place by means of screws 37 or otherwise. One face of the pressure plate 36 is roughened as shown at 38 and this roughened face is adapted to coeperate with the roughened upper face 39 of the base 9. Coacting with the arm 34 to elevate the same is a spring 40. A foot lever 41 is fulcrumed at 42 on the anvil or support and coacts with the arm 34 to depress the same against the action of the spring 40.

In practical operation, the angle lever 17 is swung downwardly until the arm 19 and the die 21 are disposed in a substantially horizontal position. Then the bar 1 of metal which is to be bent and shaped is I placed on the base 9 and enters the groove 23 in the die 21, the bar of metal abutting against the stop 25. The adjustable feature of the stop 25 now is obvious. The foot of the operator is placed on the lever 11 and the latter coacts with the arm 34, swinging the same downwardly against the action of the spring 40 until-the angle plate or head 36 lies above the base 9, the roughened face 38 of the part 36 and the roughened face 39 of the base 9 coacting to prevent the ma- Copies of this-patent may be obtained for expafiils intethe of the groove 23 to form the en Fi 8. The metal, of course, is handled in a hea c condition.

Having thus described the inventiomwhat is claimed is 7 1. In a device. for bending and shaping metal, a base and a lever mounted to swing with respect to the base to eifect a bending of the metal, the lever being cut away adjacent the base'to permit a lateral expansion of the metal adjacent its point of bend- 111g.

2. In a device for bending and shaping metal, a base; a lever mounted to swing with respect to the base to effect a bending of the l ar ed portion metal, the lever being cut away adjacent the base to permit a lateral expansion .of the metal adjacent its point of bending; a compression member comprising parts which are threaded together, whereby one of said parts may be adjusted toward and away from the lever, theother of said parts being pivotally connected with the base; a spring coacting with the first specified part of the compression member to elevate the compression member; and a movable element under the control of an operator and bearing upon the first specified part of the compression member to depress the compression member, the spring and the movable element coact ing with the first specified part of the compression member to prevent relative rotation between the parts of the compression mem ber.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
